Tommy Westphall Universe

The Tommy Westphall Universe, also known as the Tommy Westphall Hypothesis, is an idea of shared universe among hundreds of television shows.

The origins of this hypothesis are rooted in Tommy Westphall from St. Elsewhere.

The concept saw its first form in Six Degrees of Tommy Westphall. Currently, it has grown to the rank of internet meme. The central source for adherents is The Multiverse.

Given the fame of the hypothesis, it has quite naturally gathered differing opinions. The most negative of these have created counterarguments, the most notable of which is Six Objections to the Tommy Westphall Hypothesis.

Other opinions exist without denying the concept. This creates widely varying interpretations. Some reject cartoon crossovers, while others accept them under somewhat stricter guidelines. Most insist that the phenomenon be restricted to television, but a select few allow crossovers to branch through nearly all types of fiction.
